IMPROVEMENT m LUBRICATORS.

Specification forming part of Letters Patent No. 176,422, dated April25, 1876; application filed November 12, 1873.

To all whom it may concern:

Be it known that I, GEORGE B. BRYANT, of Pottsville, in the county ofSchuylkill and State of Pennsylvania, have invented 'a new I andImproved Lubricator; and I do hereby declare the following to be a fulland exact description of the same, reference being had to theaccompanying drawings, forming part of this specification, in whichFigure 1 is a perspective view, and Fig. 2 is a vertical section.

Similar letters of reference in the accompanying drawings denote thesame parts.

This invention is an improvement upon my car-wheel lubricator patentedOctober 31,] 871, N 0. 120,489, and is designed to extend theapplication of the principles of construction there in shown toindependent attachable and de-- tachable oil-cups for all kinds ofmachinery.

To this end, my present improvement consists it} the new article ofmanufacture herein shown, having the spring-follower, fibrous material,and oil-reservoir, combined with a small attachable and detachable cup,substantially as I will now proceed to describe.

In the drawings, G is the oil-cup, made of glass, metal, or othersuitable material, having an oil-reservoir within it, a screw-stem, c;at its lower end, and a screw-cap, c, suitably packed, at its upper end.In the recess "at the lower nd of the oil-chamber is-a small quantity ofcotton-waste, sponge, or other fibrous material, e, upon which aperforated plate, m, which may form a part of the spring, it preferred,is preserved by a spring, 8, which may be held in place by the screw-capc, or by a small cross-bar or plate, a, which may be adjustable for thepurpose of increasing or diminishing the pressure of the spring.

The oil flows from the chamber 0 to the journal through the sponge e andoutlet t, its delivery being in inverse ratio to the pressure of thespring 8 upon the sponge.

This pressure is to be carefully adjusted, so that when the machinery isat rest, and the oilcup is not jarred, the steady pressure of the springupon the sponge will prevent the oil from flowing out at all; but whenthe machinery is in motion, and the oil-cup subject to being jarredthereby, the vibration of the spring will allowsoine portion of the oilto work under the plate m into the sponge, and thence through theaperture t onto the journal.

The device is especially adapted for use in connection with commonroad-carriages, coalcars, locomotives, and other vehicles and machineryhaving sufficient vibration to operate the spring 8, as described.

Having thus set forth the nature of my invention, I claim- GEORGE E.-BRYANT.
